You can go here to view a video on the NHLPA site with player reaction around the NHL about the death of Wade Belak.
While the video doesn't shed any new light on the facts surrounding Belak's tragic death, it is worth noting the comments from players about the need for improved identification of and assistance for problems that players may have. I would look for this to be brought up in the next CBA negotiation.
Also note the shot of the outside of the Air Canada Centre in Toronto at the 4:25 mark of the video. Toronto is where Wade spent the majority of his professional career.
A stick tap to my friend @dani3boyz who sent this video to me.
